Two suggestions:
The first is to take more advantage of your diamond membership by doing tactics courses over at the ChessMentor. There are around 15 courses by GM Patrick Wolff alone that each teach a seperate motif. Tactics are harder if you don't know what to look for. If you're more of a video person, IM Danny Rensch covers the same material.
Second is to kick over to V3 where you can practice unrated and review puzzles you've missed or particular motifs. That's Try the new Chess.com at the bottom of the page if you've never been there. Good luck and have fun!
